MAGIC adj. 1. As yet unexplained, or too complicated to explain.
(Arthur C. Clarke once said that magic was as-yet-not-understood
science.) "TTY echoing is controlled by a large number of magic
bits." "This routine magically computes the parity of an
eight-bit byte in three instructions." 2. (Stanford) A feature
not generally publicized which allows something otherwise impossible,
or a feature formerly in that category but now unveiled. Example: The
keyboard commands which override the screen-hiding features.
